IPC: G01P3/50
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To solve the problems on the technique for detecting the real vehicle speed of the machine body according to the ultrasonic Doppler effect in which the ultrasonic signals are emitted toward the ground surface and the reflection signals turned from the ground surface are received and the ground speed is calculated from the change in the frequency caused by the Doppler effect, but in the case of the work vehicles for agriculture, particularly the vehicles running in the rice paddies filled with water, the conventional ultrasonic Doppler type sensors have defective tendency to be susceptible to water with many misdetections and the practical use is difficult. SOLUTION: In this invention, a plurality of ground speed sensors are arranged in the front and the rear of the machine body in order to detect the change in the distance between the machine body and the ground surface and the ground speed is detected on the basis of the deviation of the phase of the detected values in the ground speed sensors in the front and rear of the machine body.
